An Application of Non-response Bias Reduction Using Propensity Score Methods
Normal distribution is widely used in many applications. The problem of testing whether observations come from a normal distribution has been studied extensively by many researchers. Our main goal in this article is to present a simple test procedure for testing multivariate normality.
متن کاملAn Application of Non-response Bias Reduction Using Propensity Score Methods
In many statistical studies some units do not respond to a number or all of the questions. This situation causes a problem called non-response. Bias and variance inflation are two important consequences of non-response in surveys. Although increasing the sample size can prevented variance inflation, but cannot necessary adjust for the non-response bias. Therefore a number of methods ...
متن کاملReducing Bias in Cancer Research: Application of Propensity Score Matching
In cancer observational studies, differences between groups on confounding variables may have a significant effect on results when examining health outcomes. This study demonstrates the utility of propensity score matching to balance a non-cancer and cancer cohort of older adults on multiple relevant covariates. This approach matches cases to controls on a single indicator, the propensity score...
متن کاملDouble propensity-score adjustment: A solution to design bias or bias due to incomplete matching
Propensity-score matching is frequently used to reduce the effects of confounding when using observational data to estimate the effects of treatments. Matching allows one to estimate the average effect of treatment in the treated. Rosenbaum and Rubin coined the term "bias due to incomplete matching" to describe the bias that can occur when some treated subjects are excluded from the matched sam...
متن کاملUsing Administrative Databases for Research: Propensity Score Methods to Adjust for Bias
Health care and other programs collect large amounts of information in order to administer the program. A health insurance plan, for example, probably records every physician service, hospital and emergency department visit, and prescription medication—information that is collected in order to make payments to the various providers (hospitals, physicians, pharmacists). Although the data are col...
